LIBRARY

Curses Library (libcurses)

DESCRIPTION

All of these routines copy
wchstr, which
points to a string of
wchar_t
characters, directly into
the window image structure starting at the current or specified cursor position.
The four routines with
n
as the last argument copy
at most
n
elements, but no more than will fit on
the line. If
n=-1, then
all the routines copy the whole string, to the maximum number that fit on
the line or until a null terminator is reached.

The routines do not advance the position of the window cursor. They
work faster than
waddnwstr
because they merely copy
wchstr
into the window image structure. On the other hand, care
must be taken when using these functions because they:
Do not perform any kind of checking (such as for the newline
character)
Do not advance the current cursor position
Truncate the string, rather then wrapping it around to the
new line

NOTES

The header file
<curses.h>
automatically
includes the header file
<stdio.h>.

Note that all routines except
waddwchnstr
may be
macros.

The routines described on this reference page are among the MNLS Curses
functions that are not included in the X/Open Curses CAE specification. MNLS
routines are supported only for backward compatibility reasons. For new applications, Compaq
recommends the use of the routines described on the
add_wchstr(3)
reference
page.

RETURN VALUES

All routines return the integer
ERR
upon
failure and an integer value other than
ERR
upon
successful completion, unless otherwise noted in the preceding routine descriptions.
